  • the power supply circuit device for the high intensity discharge lamp lighting device is used for lighting a high intensity discharge lamp such as a lamp for a projector.
  • FIG. 4 shows a circuit diagram for a conventional high intensity discharge lamp lighting device using a high power-factor inverter.
  • a power-frequency AC power is rectified to a direct current by a rectifier including diodes D101-D104, an inductor LF, and a condenser CF, and the output is applied to a booster chopper mode sine wave converter including a choke coil L101, a switching element SW1, a diode D105, and a condenser C.
  • the booster chopper mode sine wave converter is connected to a full-bridge mode inverter INV as the load.
  • the booster chopper mode sine wave converter will briefly be explained.
  • a voltage ei' is detected by resisters R101, R102 to be fed to a multiplier MP1. This voltage is transferred to a current command reference Ii* having the same wave form as the voltage ei'.
  • a current Ii' is detected by a resister R104 and a comparator COMP1 compares Ii' to Ii* to produce a PWM signal proportional to the difference between Ii* and Ii'.
  • a lamp current detecting resister R105 detects a lamp current IL.
  • a variation ⁇ IL of the lamp current IL is obtained by a constant-current circuit, and the multiplier MP1 makes a product by ⁇ IL and ei' to produce the current command reference Ii*.
  • a feedback circuit is configured, the amplitude of Ii* varies according to the variation of IL, i.e., ⁇ IL, thereby IL is stabilized and at the same time the current waveform identical to ei' can be obtained.
  • the average current by each switching is proportional to the input voltage, removing higher harmonics of the switching wave form by means of a low pass filter consisting of an inductor LF and a condenser CF makes the wave form of the input current analog to the input voltage with regard to one cycle of the AC line as shown in FIG. 5, and the power factor becomes almost 1.
  • the booster chopper mode sine wave converter is connected to the full-bridge mode inverter INV as the load.
  • TR1-TR4 are switching transistors configuring the inverter INV.
  • the output of the inverter INV is connected to the secondary coil of a transformer T101 and a halide lamp L (HID, hereinafter) in series.
  • a timer circuit TM is activated to feed a 100 Hz starting trigger pulse to a starting pulse generator PG.
  • the starting pulse generator PG feeds a starting pulse for about five seconds, and the starting pulse is boosted to 3-5 KV by a transformer T101.
  • the timer circuit TM feeds an inverter starting signal to an oscillator OSC, thereby the oscillator OSC starts operation, whose output activates a drive circuit DCC; which in consequence activates the inverter INV.
  • the HID lamp L enters in a lighting state, transferring the state from a glow discharge to an arc discharge.
  • the inverter current i.e., the lamp current is detected by the lamp current detecting resister R105, which is fed to a control IC.
  • the control IC feeds a signal to a DRIVE CIRCUIT as the control input terminal of the booster chopper mode sine wave converter so as to suppress the lamp current if it goes high and to increase the lamp current if it goes low, thus controlling the inverter INV into a constant current.
  • the output voltage of the booster chopper mode sine wave converter decreases by the PWM operation of the booster chopper mode sine wave converter, which maintains the constant current operation.
  • the foregoing conventional inverter is well known that it has restrictions for a smaller size.
  • the lamp current will fade out to lead the lamp to an unstable operation due to the acoustic resonance effect if the inverter INV oscillating frequency is lass than 300 KHz. Therefore, the switching frequency is selected to less than some 100 Hz not inducing the acoustic resonance.
  • the switching frequency is apt to be less than 400 Hz due to the restriction of the switching elements such as the switching speed, thereby the transformer T1 is difficult to be made smaller.
  • control circuit and the drive circuit of the full-bridge mode inverter are complicated and costly.
  • the present invention provides the power supply circuit device for the high intensity discharge lamp lighting device described hereafter.
  • the power supply circuit device for the high intensity discharge lamp lighting device includes a rectifier for a power-frequency power supply, a booster chopper mode sine wave converter, a zero volt switching push pull inverter, and a high intensity lamp of a halide lamp. And, as a starting device for the halide lamp, the high intensity discharge lamp lighting device generates a high voltage (5 KV) using a resonance by a ballast choke for the inverter and a condenser connected in parallel to the halide lamp, thereby inducing a glow discharge. And, a PFM (pulse frequency modulation) circuit controls the lamp current of the halide lamp to keep it constant.
  • a PFM pulse frequency modulation
  • a re-lighting circuit after lighting works such that the control IC stops operation by a pulse-by-pulse mode current limiter of an inverter control IC, thereafter a soft starting circuit operates to generate a high voltage on the output of the inverter; when the lamp temperature is so high that the mercury vapor pressure inside the tube goes high and lighting cannot be started, the foregoing operation is repeated to achieve re-lighting.
  • the resonance by the ballast choke and the condenser connected in parallel to the halide lamp generates a high voltage (5 KV) to the output of the inverter, leading to a glow discharge.
  • the operation of the inverter becomes a blocking oscillation mode; consequently, the inverter generates a high voltage periodically until the halide lamp starts lighting.

  • FIG. 5 is a wave form chart showing wave forms of the input voltage and the current of the converter.
  • FIG. 1 is a circuit diagram showing a high intensity discharge lamp lighting device according to the present invention.
  • the power-frequency AC power supply is rectified by a rectifier consisting of diodes D1-D4 into a direct current, and the output is applied to a booster chopper nodesine wave converter including a choke coil L2, a power MOSFET Q2, a diode D5, and a condenser C2.
  • a voltage resonant inverter is connected to the booster chopper mode sine wave converter as the load.
  • the booster chopper mode sine wave converter will briefly be described.
  • a voltage ei' is detected by resisters R8, R9 to be fed to a multiplier MULT. This voltage is multiplied by an output of an error amplifier to produce the output of the multiplier MULT.
  • a current running through the choke coil L2 is detected by a resistor R3, and the voltage across the resistor R3 is distributed to a current sense logic circuit. If this voltage exceeds a nominal voltage determined by the output VMO of the multiplier MULT, the PWM goes OFF; consequently, the gate of the power MOSFET Q2 turns OFF.
  • An, output of a current detecting winding Ns2 of the choke coil L2 is fed to the current sense logic circuit through a resistor R6.
  • a resistor R7 is a starting resistor.
  • a resistor R1 is a gate drive resistor for the power switching element Q2, a diode D6 is to pull down charges stored between the gate and the source of the power switching element Q2. Since the output voltage of the booster chopper mode sine wave converter is made constant, the input voltage of the zero volt switching push pull inverter connected as the load becomes constant; and usually the halide lamp is used without adjusting intensity (at a constant lamp current), the lamp power is controlled constant, and the switching frequency of the inverter becomes constant.
  • L1 is a ballast choke having a primary coil np1 and a secondary coil ns2, of the zero volt switching push pull inverter.
  • IC1 is a zero volt switching power supply controller composed of an integrated circuit. This IC1 is available on the market, for example, Micro Linear ML4816.
  • Q1, Q3 are power switching elements (power MOSFET).
  • a resistor R20 is a starting resistor, when the system is powered, the zero volt switching power supply controller IC1 is supplied with power to operate.

  • a starting condenser C5 is connected between the output of the ballast choke L1 and the ground.
  • the foregoing condenser C5 is connected in parallel to a halide lamp L connecting in series with a current detecting condenser C7.
  • the present invention applies the zero volt switching push pull inverter to drive the halide lamp and performs the constant current control.
  • the condenser C11 is connected to the soft start controller SSC.
  • the output of the soft start controller SSC is in HIGH level directly after the power turning ON. Since the output is connected to the control input of the voltage controlled oscillator VCO, the output of the voltage controlled oscillator VCO goes higher than that in the steady state operation. As the voltage across the condenser C11 increases, the output of the soft start controller SSC is designed to decrease; and the oscillating frequency of the voltage controlled oscillator VCO gradually lowers.
  • the method of starting the HID lamp will be described. Immediately after the AC power is supplied, the HID lamp L is not lighted and the internal impedance of the lamp is high. Selecting the value of the ballast choke L1 and the starting condenser C5 so as to set the resonance frequency by these two components to, for example, 300 KHz will produce a high voltage (5 KV) of a 300 KHz sine wave across the condenser C5, thereby starting a glow discharge in the HID lamp L.
  • the choke coil L1 is a ballast inductor loaded with the voltage difference between the output (connecting point of the source of the power switching element Q1 and the drain of the power switching element Q3) voltage of the inverter and the discharge maintaining voltage.
  • R17, R18 are gate drive resistors for the power switching elements Q1, Q3; D9, D10 are to pull down charges stored between the gate and the source of the power switching element Q1 and 03, respectively.

  • R20 is a starting resistor.
  • the zero volt switching power supply controller IC1 will be described in detail with reference to FIGS. 1 and 3.
  • the discharge current (lamp current) of the HID lamp L is increased by any reason, the output of the error amplifier OPA increases and the oscillating frequency of the voltage controlled oscillator VCO goes high.
  • the fall of output of the voltage controlled oscillator VCO puts the one-shot MB of the one-shot multi-vibrator MB into the set state, the output of which goes HIGH level.
  • the fall of the phase-reversed output voltage controlled oscillator (bar) of the voltage controlled oscillator VCO puts the one-shot MB (bar) of the one-shot multi-vibrator into the set state, the output of which goes HIGH level.
  • a resistor R12 and a condenser C12 are to determine the pulse width of the output of the one-shot multi-vibrator, and the output of the one-shot MB is maintained in a high level during the time Toff determined by the Lime constant. That is, with maintaining the Toff constant, pulse frequency control is performed which varies the oscillating frequency (i.e., switching frequency) of the voltage controlled oscillator VCO.
  • Vds exceeds the power supply voltage VO2
  • a body diode of the power switching element Q1 turns ON, Vds is clamped to the power supply voltage VO2.

  • a transformer T1 is for gate drive of the power switching element Q1.
  • the output of the comparator COMP1 becomes a high level to put the flip flop FFi into a set state.
  • the output of the flip flop FF1 controls the constant current source IS to turn ON and OFF, and the flip flop FF1 is to set, and output Q is to high the constant current source IS is opened and charges a condenser C10.
  • the flip flop FF1 is reset every one cycle of the oscillating frequency. If the power switching element Q3 continues to flow an excessive current, the voltage across the condenser C10 goes high.
  • the condenser C10 is connected to the +input of the comparator COMP2, when the voltage exceeds the threshold voltage 3.2 V of the comparator COMP2, COMP2 becomes a high level; closing AND gate, AND1, and AND2 leads the output of the driver DB to a low level.
  • the oscillation stops, and the power supply voltage to the control IC IC1 lowers.
  • IC1 starts operation by the starting resistor R20, the foregoing operation is repeated. That is, it starts a blocking oscillation mode. In this state, the temperature inside the tube of the HID lamp L falls, mercury vapor pressure lowers to increase the internal resistance, thus maintaining the state to finally enabling a glow discharge.
  • a power MOSFET having a lower withstand voltage having a lower ON resistance
  • a simplified starting circuit can be configured using a ballast choke and a condenser. Utilizing the pulse-by-pulse mode current limiting function of the zero volt switching power supply controller available on the market realized the restarting of the HID lamp in a blocking mode. As, the input voltage of the inverter is made constant the switching frequency of the inverter can be made constant, thereby reducing interference to other equipment.
